CONVEYER SYSTEM.

. SPECIFICATION forming part of Letters Patent No. 714,357, dated November 25, 1902.

Appliationled April 10, 1902.

To CLZZ whom it may concern:

Be it vknown thatl, HIRAM W. BLAIsDELL, a citizen ofthe United States, residing at Yuma, in the county of Yuma, Territory of Arizona, have invented a new and useful Oonveyer System, of which the following is a specification.

This invention relates to a conveyer sysf tem, and particularly to such a system Where;

in a main and an auxiliary conveyor are em-V ployed and some ofthe objects of the invention are to provide ai conveyer system that is simple in construction and positive and effective in operation1 y Another object of theinvention is to pro vide .such a systemwherein the main con- Veyer occupies a plane below that of the auxiliary conveyer, upon which it discharges.

A further object of the invention is to provide a conveyer capable of occupying dierent planes, so as to discharge upon elevations.

It is also an object of this invention to provide an endless main "conveyor arranged to discharge upon a superimposed cross auxilary conveyor constructed to be transported above the line of travel of said main conveyor and provided with means traveling therewith to effect said discharge.

With these and other objects in view the invention consists, essentially, in the construction, combination," and arrangement of parts substantially asl more fully described in the following specification and illustrated in the accompanying drawings, forming part of this application, in which- `Figure 1 is an elevational view, partly in section,showing an end discharge. Fig. 2 is a fragmental view illustrating an intermediate discharge. Fig. 3 is an elevational view at right angles to that of Fig. 1, showing the `manner of elevating a portion of the main conveyer.

or framing 2, and upon the timbers 1 are se` cured track-rails 3 to receive and support Serial No. 102,294. (No model.)

wheels 4, carried by axles 5, Figs. 1 and 37 provided with bifurcated bearings ,6, supporting channel-irons 7 ,Whereon rest I-beams 8, substantially as shown in said figures.

Upon the I-beams 8 are preferably secured cross-beams 9, supporting timbers or a platform 10, whereon are preferably secured upper rollers or pulleys 11,12, and 13 and lower rollers or pulleys 14, 15, and 16, the former desirably embracing a group of rollers arranged in dilferent planes in order to provide a longitudinal curvature to the endless auxiliary conveyer 23, passing thereover and over the driving and guiding pulleys or rollers 17 and 18, respectively, at the ends of the traveling structure Vor bridge just described, the former being actuated, preferrality of pulleys or rollers 27, Figs. 1 and 3,

any number of sets whereof maybe employed to receive and support the lower or empty lead of the main conveyer 28, and mounted in a curved position upon the top portion of the trough 25 are sets of pulleys or rollers 29, Figs. 1 and 3, to receive and support the upper or loaded lead of the main conveyer 28 (except where the same is elevated) in such a manner as to impart a longitudinal curvature thereto to prevent the lateral discharge of the material transported thereby.

Formed on or connected with the platform 10 or in any other suitable manner are uprights 30, to which and to said platform are preferably secured inclined members or a frame 31, Fig. 3, constructed to support sets of curved pulleys or rollers 32, coustructedto receive and support a portion of the main conveyer 28, which passes thereover and over l' a large discharging pulley or roller 33, preferably mounted upon the uprights 30, suh

stantially as shown at 34, Fig. 3, and thence IOO or roller (not shown) and back over the sets of straight rollers 27, Figs. 1 and 3 of the drawings.

By means of the construction just described a minor portion of the main conveyer, preferably that adjacent to the traveling bridge or structure, is temporarily elevated from the sets of pulleys or rollers 29, as shown at the left of Fig. 3, and passes up over the sets of pulleys or rollers 32 on the frame 31 and over the discharge pulley or roller 33 and down under the pulley or roller 35 back to the sets of pulleys or rollers 29, which is its normal plane of operation.

It will be understood from the foregoing description,when taken in connection with Figs. 1, 3, and 4 of the drawings and particularly the latter figure, which is a perspective diagrammatic View illustrating the relation of the main and auxiliary conveyors and the method of discharge from the lower main conveyer upon the superimposed auxiliary conveyer,that the mechanism for elevating a portion of the main conveyer moves with the traveling structure or bridge, which is movably supported upon the wheels 4 running on the track 3, and that as said structure is progressed the elevated portion of the main conveyer is likewise advanced, so that the same always discharges its load upon the auxiliary conveyer.

Formed on or connected with the standards or uprights 30 is a hood or casing 37, constructed to receive the impact of the load discharged by the main conveyer while passing around the pulley or roller 33 and to direct the same upon the auxiliary conveyer 23, preferably carried by pulleys or rollers 17 and 18, as before explained, and the auxiliary conveyer 23 transports the material discharged thereon to the point or points for depositing the same, which points may be varied by progressing the bridge or structure supporting the auxiliary conveyer 23, as will be readily understood.

In Fig. 1 of the drawings the auxiliary conveyer 23 is constructed to discharge at the end of the bridge or structure; but in Fig. 2 the driving-pulley 17 is moved nearer the guiding-pulley 18, and the discharge of the material is effected intermediate of the length of the bridge or traveling structure, which is especially used when the material employed is to be discharged directly into tanks or vats.

The operation of the construction hereinbefore described and shown will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following explanation thereof. The material to be transported is deposited upon the main conveyer 28 and is carried thereby over the pulleys or rollers 29 until the main conveyer with its load reaches the pulleys or rollers 32 upon the inclined frame 31 and passes thereover up and over the discharging pulley or roller 33 upon the uprights or posts 30 and within the hood or casing 37, which latter actsto receive and direct the material discharged therein by the passage of the main conveyer 28 over said discharging-pulley upon the auxiliary conveyer 23, which conveys the material discharged thereon by the main conveyer to a point or place of final discharge, as will be readily understood. From the dischargingpulley 33 the main conveyer descends to and around the pulley or roller 35 and thence to and over the sets of curved pulleys 29 upon the upper surface of the frame or trough 25 and returns over the straight pulleys 27, mounted in said trough, as before explained. If it is desired to finally discharge the material at the end of the traveling structure or bridge, then the construction shown in Figs. 1 and 3 may be employed; but if an intermediate discharge of the material is necessary the construction illustrated in Fig. 2 can be used.

Referring now to the construction illustrated in Figs. 5 and 6 of the drawings, there is illustrated a modified form of the construction hereinbefore described and shown, wherein Figs. 5 and 6 illustrate an elevating device or tripper, which is mounted independently of the bridge and is preferably supported upon wheels 60, traveling upon rails 61, desirably mounted upon the frame 25, and a platform 63 may be mounted above the Wheels 60 and uprights 30 may be secured to said platform, and the uprights may support a discharging pulley or roller 33, substantially as before described and shown.

Preferably connected with the platform 63 and with the uprights 30 are inclined members of a frame 31, Fig. 6, constructed to support sets of curved rollers 32, adapted to receive and support a portion of the main conveyer 28, which passes up thereover and over the discharge pulley or roller 33, and thence down under a pulley or roller 35, desirably journaled or mounted beneath the platform 63, and from the roller 35 the main conveyer 28 passes out over the sets of curved rollers or pulleys 29 to and around a tail pulley or roller (not shown) and back over the sets of straight rollers 27, as before described.

Formed on or connected with the standards or uprights 30 is a hood or casing 37, constructed to direct the discharged material upon the auxiliary conveyer 23, substantially as before explained, and in the construction shown in Figs. 5 and 6 of the drawings the elevating device or tripper may be removably connected with the bridge, as indicated at 75, so as to travel therewith when desired and to be disconnected therefrom and transported singly along the line of travel of the main conveyer to whatever point it is desired to discharge the material from the main conveyer.

In Figs. 5`and 6 the bridge or traveling structure is preferably provided with tracks or rails 64, whereon travel wheels 65, supporting a truck 66, carrying inclined mem- ICO IIO

714,35*? l is bers of a frame 67, supporting sets of curved rollers 68, and said inclined frame preferably terminates in a horizontal extension 69, supported by uprights 70. (See Figs. 5 and 6.)

Mounted upon the extension 69 is a large dis-4 charge pulley or roller 71, partially inclosed in a hood or casing v'72), preferably terminating in a discharge-spout 7 3 to receive and direct the material discharged from the auxiliary conveyer 23, which passes over the end `pulley 18, the upper pulley 11, the sets of l curved pulleys or rollersS, over the dischargepulleyl, thence down over the guide pulley or roller '7a upon the truck 66, then over the upper pulleys or rollers 13, the end pulley 17, and returning over the bottom rollers or pulleys 14, 15, 16, and 75 to the end pulley 18. elevating device or tripper for the main conveyer can be detached from the bridge or caused to discharge the material at any point throughout the length of the bridge, as will be readily understood.

It is not desired to confine this invention to the specific construction, combination, and arrangement of parts herein shown and described, and the right is reserved to make all such changes in and modifications of the same as come within the spirit and scope of the invention.
